Arrow vet John Barrowman, who has played Malcolm Merlyn through several seasons of the show, has reportedly been promoted to series regular not just on the Star City-centric show, but all other DC shows on the CW, according to TVLine.
Barrowman's new contract will also reportedly allow him to cross into other CW shows, including Flash, DC's Legends of Tomorrow, and even Supergirl, similar to Wentworth Miller's recent deal to play Captain Cold as a floating character. At the time, overall producer Greg Berlanti said this unique strategy is done in part to emulate the interconnected nature of comic books.
“What it really emulates to us is the comic books themselves, where there really are a cast of characters,” Berlanti said of Miller's new contract. “In success, we hope to continue with other characters finding their way across all the shows.”
Arrow season 5 premieres October 5 on CW.
